Define "good".
Hydrogen is not an available fuel - it must be made (never 100 % efficient).
It is a way to store energy - but the density of storage is low ... unless you liquify it. A costly procedure. And the infrastructure is not there to supply all the cars on the road.
BUT - burning it is non polluting.
Hydrogen is already in use in some experimental cars and motorbikes, it's only emission is water which makes the fuel very environmentally friendly, more research and development is needed before it becomes a viable option for all.
If you look around you will not find many hydrogen stations or cars. This thing is not even beguining to be true.
No because if the car caught fire it is more dangerous than petrol as it is used as rocket fuel.
Yes, this is a probable solution for the future.
Yes
Some industrial chemistry gives hydrogen as a by product fro example the electrolysis of brine (salt water) would give hydrogen. We can also electrolyse water to give hydrogen for fuel.
yes
Not at all. Instead, they are being used in car engines as an alternative fuel as it is a green fuel (non - pollutant). But, the drawback is that you may have to change / modify the engine of your car to use this type of green fuel.
yes
There are 3 main types of a Fuel Cell. 1. Hydrogen Fuel Cell. This is the main one people use nowadays. 2. Solid Oxide Fuel Cell. 3. Alkaline Fuel cell. Made from Alkaline metals.
they should because otherwise the car won't move
No, there is no combustible substance there. However some car companies have concept vehicles that use hydrogen as a fuel; Hydrogen is a gaseous mix of water and oxygen.
I suppose that is not possible; and also is not economic.

Hydrogen is a gas and would have to be stored under high pressure in a car to be used as a fuel. In the event of a crash with a car containing a cylinder of pressurized hydrogen the cylinder could rupture and any sort of ignition would cause the very flammable hydrogen to catch resulting in an explosion. A cylinder containing hydrogen in a car is a potetnial bomb. This is why the use of hydrogen is still mostly unseen in the automotive industry
Petrol
Bio-diesel possibly or maybe we'll just have to use solar energy and Hydrogen powered fuel cells (the water produces electricity for the car)
No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
A fuel cell operates on the principle of reversing the process of electolysis of water. The fuel cell recombines hydrogen and oxygen to create energy and water.
Neither car is available and most likely will not be for some time, if ever. Fuel cell technology is probably closer to a reality. The major disadvantage is that they produce no fuel savings and are not a positive for our environment. Hydrogen is derived by stripping it from natural gas. The net result is that we use fossil fuel to power the fuel cell car.
